Not always, at least for me, with which version did you check?

lanx@nc10-ubuntu:~$ perl -e 'CORE::say("bla")'
CORE::say is not a keyword at -e line 1.
lanx@nc10-ubuntu:~$ perl -E 'CORE::say("bla")'
bla
lanx@nc10-ubuntu:~$ perl -version

This is perl, v5.10.0 built for i486-linux-gnu-thread-multi

As a minor nitpick, according to the definitions in perlglossary I'd rather use built-in and not operator to describe say, though the differences are indeed fuzzy.
